Limestone Turn Into Marble

If the limestone is pure a white marble is formed.

Limestone turn into marble.

Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Limestone change into marble when a great heat and pressure come from the under of the earth change into marble. With continued metamorphism these crystal seeds grow while any clay deposits in the limestone transform into silicate structures such as mica.

It is composed primarily of the mineral calcite caco3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite. Limestones may include layers of clay or sand which may form the attractive flow banding and colours found in decorative marble.

The main difference between limestone and marble is that limestone is a sedimentary rock typically composed of calcium carbonate fossils and marble is a metamorphic rock. Limestone forms when shells sand and mud are deposited at the bottom of oceans and lakes and over time solidify into rock. Marble forms when sedimentary limestone is. The calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow.

It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. When limestone is buried and put under intense heat and pressure why does it turn to marble instead of thermally decomposing into calcium oxide and carbon dioxide. Because marble is a fairly soft material only a three on the mohs hardness scale it is easy to cut and carve. When the heat and pressure hits the limestone calcite seed crystals form.
